Influenza (Flu) Vaccine

Flu vaccine

The flu vaccine helps protect against flu, which can be a serious or life-threatening illness. It’s offered on the NHS every year in autumn or winter to people at higher risk of getting seriously ill from flu.

Who should have the flu vaccine

The flu vaccine is recommended for people at higher risk of getting seriously ill from flu.

It’s offered on the NHS every year in autumn or winter.

You can get the free NHS flu vaccine if you:

  • are aged 65 or over (including those who will be 65 by 31 March 2027)
  • are aged 18 to 64 and have certain long-term health conditions
  • are pregnant
  • live in a care home
  • are the main carer for an older or disabled person, or receive a carer’s allowance
  • Having the flu vaccine at the same time as other vaccines
  • You can have the flu vaccine at the same time as other vaccines such as the COVID-19 and shingles vaccines.
  • It’s not usually given at the same time as the RSV vaccine, but you can have them at the same time if a doctor or nurse thinks it’s needed.

Side effects of the flu vaccine

The most common side effects of the flu vaccine are mild and get better within 1 to 2 days.

They can include:

  • pain or soreness where the injection was given
  • a slightly raised temperature
  • an aching body

More serious side effects such as a severe allergic reaction (anaphylaxis) are very rare. The person who vaccinates you will be trained to deal with allergic reactions and treat them immediately.

The injected flu vaccines used in the UK do not contain live flu viruses. They cannot give you flu.

How well the flu vaccine works and how long it lasts

The flu vaccine aims to protect you against the most common types of flu viruses.

There’s still a chance you might get flu after getting vaccinated, but it’s likely to be milder and not last as long.

The vaccine usually takes up to 14 days to work.

Protection from the flu vaccine goes down with time and the types of flu virus the vaccine protects against are updated each year. This is why it’s important to get the flu vaccine every year.
